Invasive tick that can be deadly for cattle causing concerns among researchers
STILLWATER, Okla. (KFOR) — A heads up for cattle producers: there's a deadly tick in the United States, and researchers at Oklahoma State University are concerned.
'These ticks can be so high on a single cow that they can actually result in so much blood loss that the animal can die from that,' Dr. Jonathan Cammack, Assistant Professor at OSU and State Extension Specialist for Livestock, Entomology, and Parasitology, told Nexstar's KFOR.
Dr. Cammack said the Asian Longhorned Tick, also known ALT, is native to East Asia. It was first seen in the U.S. a decade ago and has since been detected in more than a dozen states: Arkansas, Connecticut, Delaware, Illinois, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Missouri, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, and West Virginia.
It was discovered in Oklahoma last year on cattle in Craig County.
'It's not going to have that bright white spot on it like a lone star [tick]. And they're also going to be very small, about half the size of the normal tick that we're usually expecting to see at this time of year,' said Dr. Cammack.
They're also concerned with how fast the ticks can reproduce.
'They can reproduce asexually, so they don't have that added challenge of locating a mate in the environment,' said Dr. Cammack. That means a female can lay up to 2,500 eggs on one animal, which can then consume enough blood to be deadly.
Now, they're hoping research can help with ideas to slow or stop the spread.
'There's a project going on at the vet school where they're collecting ticks that are suspected to be Asian Longhorned Ticks, and then they're testing them for the presence of this pathogen,' said Dr. Cammack. The pathogen is the Theileria orientalis Ikeda genotype, which can be detrimental to cattle.
This year, the team is looking for new cases of the tick, and they hope Oklahoma ranchers will help them with surveillance. Dr. Cammack recommends that animals are checked regularly — maybe not daily, but more than once a year — for the tick.
If you see it on your cattle, it's recommended that you call your local veterinarian. If you live in an area where the tick has become established, there may be other steps you're advised to take.

Snake season: What to do if a venomous snake bites you?
OKLAHOMA CITY (KFOR) — As the temperatures climb and many head outdoors to enjoy the sunshine, it's also waking up some slithery visitors. The Oklahoma Poison Center is already starting to see an uptick in calls. In 2024 alone, The Oklahoma Poison Center helped manage 363 snake bites across the state. 160 copperhead bites 38 rattlesnake bites 12 cottonmouth bites 102 bites from unidentified venomous snakes 34 unknown snake bites (venom status undetermined) 15 non-venomous snake bites 2 bites from exotic snakes LOCAL NEWS: OSU researching Asian Longhorned Tick that can be deadly for cattle The Oklahoma Poison Center says they do not need to know what type of snake bit you. 'Just leave it alone, get out of the area and our anti venom that we have here in Oklahoma will actually cover all venomous snakes,' said Kristie Edelen, managing director, The Oklahoma Poison Center. Edelen says to never use tourniquets, ice or extraction tools. Just head straight to the emergency room. You should also remove any jewelry or tight clothing. 'When it comes to snake bites, we have a saying that time is tissue,' said Edelen. She says that waiting too long can lead to permanent damage. The Oklahoma Poison Center says it's not just snakes you have to look out for this time of year, but also spiders. 'Probably the biggest thing that we're seeing here in Oklahoma right now is our brown recluse bites, just people specifically having things like rashes and muscle pains,' said Edelen. Scorpion stings can also happen with the warmer weather, but they're rarely dangerous. When in doubt about a bite, Edelen says the best thing you can do is call The Oklahoma Poison Center at 1-800-222-1222. Copyright 2025 Nexstar Media, Inc. All rights reserved.
